Expert Solution
Step 1

Given:

Percent of phosphorous = 18.28 %

Percent of sulfur = 18.93 %

Percent of chlorine = 62.78 %

molar mass of the compound = 169.4 g/mol

molar mass of phosphorous = 30.97 g/mol

molar mass of sulfur = 32.065 g/mol

molar mass of chlorine = 35.45 g/mol

 

let mass of compound be 100g.

100 g of compound contains 18.28 g of phosphorous, 18.93 g of sulfur and 62.78 g of chlorine.
